AP2501A/AP2511A Green 2.5A SINGLE CHANNEL CURRENT - LIMITED POWER SWITCH Description Pin Assignments The AP2501A and AP2511A are single channel current-limited integrated high-side power switches optimized for Universal Serial (Top View) (Top View) Bus (USB) and other hot-swap applications. The family of devices GND NC 1 8 GND NC complies with USB standards and is available with both polarities of 2 7 Enable input. IN OUT IN OUT 3 6 OUT IN OUT IN The devices have fast short-circuit response time for improved 4 5 EN FLG overall system robustness, and include integrated output discharge EN FLG function to ensure completely controlled discharging of the output U-DFN3030-8 (SO-8) Type E voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of (Top View) short circuit, and offer reverse current blocking, over-current, over- (Top View) GND 1 8 NC temperature and short-circuit protection, as well as controlled rise IN 2 7 OUT time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false overcurrent 3 6 IN OUT reporting and does not require any external components. 4 5 EN FLG MSOP-8/MSOP-8EP All devices are available in SO-8, MSOP-8, MSOP-8EP, Note: Latter with exposed pad U-DFN2020-6 U-DFN3030-8 and U-DFN2020-6 packages.
